£10m cost of failure
Failure in Europe this season will cost Arsenal at least £10m and also the chance of a potential jackpot well in excess of £70m for any English club that wins the Champions League.
A record-breaking UEFA prize-fund, partially funded for English clubs by the new BT Sport television deal, means that this season will be the most costly yet for teams failing to reach the last 16.
Arsenal are already guaranteed £8.84m for reaching the group phase, and each win at this stage of the competition is now worth £1.11m.
That means the poor performances against Zagreb and Olympiakos have cost Arsenal £2.22m, with a further £4.44m at stake in their remaining four group games.
Simply reaching the last 16, as Arsenal have done in each of the past 15 years, is then worth at least £4.05m, with the fund rising through the knockout phase all the way up to £11.06m for the winners. The most that a club can accumulate from basic prize money is £40.17m.
